If you draw a trapezoid with 14 cm, 9 cm as the base, 13 cm, 7 cm as the waist, can you draw this trapezoid? Why?

If you draw a trapezoid with 14 cm, 9 cm as the base, 13 cm, 7 cm as the waist, can you draw this trapezoid? Why?

If you can't draw it, first of all, make a parallel line of waist through a vertex to form a triangle. The lengths of the three sides are (14-9), 13 and 7 respectively. Obviously, 5 + 7 is less than 13. There is no triangle, so you can't draw this trapezoid

Please help to solve the following math problems
70 numbers are arranged in a row. Except for the two numbers at the two ends, three times of each number is exactly equal to the sum of the two numbers on both sides. The leftmost numbers in this row are as follows: 0, 1, 3, 8, 21,... Do you know how much it is divided by 6?

Just look at how many cycles the remainder is: 0,1,3,2,3,1,0,1,3 Six count one cycle
So the 70th digit is divided by 6 to 2
